Literally the word asphyxia means pulseless, and was for a long time only used in that sense, but is now applied generally to all cases of suspended animation. It is produced by the non-conversion of venous or blue blood of the lungs into arterial, or red blood. Death is caused in all cases from want of oxygenized blood, and the stagnation that results in the pulmonary capillaris. There are several varieties of asphyxia; and as life can in many cases be revived, I shall state the procedure of resuscitation in each case.
